Application filed April 21, 1928. Serial No. 271,943.

The present invention relates to a cotton chopper attachment for two rowcultivators and has for its prime object to provide a cotton chopperwhich may be operated from either wheel of the one or two row cultivatorand may be mounted in a unitary manner with the cultivator framestructure.

Another very important object of the invention resides in the provisionof an attachment of this nature which is exceedingly simple in itsconstruction, strong and durable, inexpensive to manufactureand install,easy to manipulate, adjustable, and thoroughly efficient and reliablefor the purpose intended.

l/Vith the above and numerous other objects in view aswill appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing:

Figure 1 is a vertical longitudinal section through a two row cultivatorshowing my attachment thereon,

Figure 2 is a fragmentary rear elevation of the cultivator showing myattachment thereon,

Figure 3 is a vertical detail section taken substantially on the line 33Figure 2,

Figure 4 is a detail horizontal section taken substantially on the line14 of Figure 2,

Figure 5 is a fragmentary detail front elevation showing particularlythe control means for the attachment,

Figure 6 is an enlarged detail section taken subistantially on the line6-6 of Figure 3, an

Figure 7 is a bottom plan view of the cotton chopper blade structure.

Referring to the drawing in detail it will be seen that the two rowcultivator illustrated in the accompanying drawing for the purpose ofexemplifying the utility of my attachment includes among other elementsan arched cross frame 5 with the usual stub axles 6 extending outwardlyfrom the extremities thereof and on which are journaled the wheels 7.

I mount a cross bar 8 between intermediate portions of the dependingside legs of the cross frame 5 and clamp a bearing to the center of thetop portion of the cross frame 5. A bearing 10 is secured to the centerof the bar 8 in registry with the bearing 9.

A shaft 11 is rotatable and slidable in the bearings 9 and 10 and islimited in its downward movement by a stock collar 12 secured theretoand against which impinges a spring 14 disposed about the upper portionof the shaft and impinging against its upper end against the bearing 9.

'Abar 16 is secured in a bracket 17 mounted on the top portion of thecross frame 5 to one side of the bearing 9 and in a bracket 18'0n thebar 8 immediately below the bracket 17 and this bar 16 extends downbelow the bar 8 and terminates in a bearing 19 in which is journaled ashaft 20, the inner end of which has a pinion 21 fixed thereto meshingwith a pinion 22 fixed to the shaft 11.

This pinion 22 is provided with an annular groove for receiving one endof a loop brace 2a the other end of which is secured in a groove of acollar 25 fixed on the lower portion of the bar 16. The collar 25 isslidable on the bar 16 and alink 26 is secured to an intermediateportion of the loop brace 24 and is pivotally engagedwith one end of afoot lever 27 which may be actuated from the ing the shaft 11 againstthe tension of the spring 14.

On the lower end of the shaft 12 there is secured a collar 33 by meansof set screws 34 or in any other quick detachable manner and on thecollar is a pair of cotton chopping blades 35 extending laterally andoutwardly with respect to each other.

In the outer end of the shaft 20 there is fixed a pinion [36. Aninternal gear37 is formed on the periphery of a plate 35. This plate 35is secured to the spokes of one of the wheels 7 by means of U-bolts 37so that. the gear 34: is concentric in respect to the wheel and mesheswith the pinion 36.

Therefore it will be seen that as the cultivator moves along, the gear34 meshing with the gear or pinion 36 rotates the shaft 20 therebyrotating the shaft 11 through gears 21 and 22. \Vhen it is desired toplace the cotton chopper out of operation it is only necessary to pressdown on the outer end of the lever 27 and the ratchet 29 will engage thedog and hold the parts in a raised position so as to unmesh the gear 22'from the gear 21 and lift the blades 35 from the ground aswill be quiteapparent;

i It is thought that'the construction 'ntility',

operation and advantages offthis invention will now be quite apparentto'those' skilledin thereof. 1 a c this art; without-a more detaileddescription The prese 't embodiment of the invention has been discloseddetail merely by way of example since in actualpraetice it attains thefeatures of advantageenumeratedas desirable in thestaternent oftheinvention and the above description], "T

It will be apparent that? changes in the" de tails of construction, andin the combination andarrangement of parts maybe resorted to withoutdeparting; from the spirit ,or scope of the nvent onas hereinafterclanned or sacrificlngany OfltS advantages.

Having thus described my invent on, what I claim as new is 1 1. In acotton chopperattachment for cul-.
